"Clunk!" I know the problem, just not the solution - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

When stepping on the brakes at any pressure other than the most gentle, there is a loud "clunk" from the rear of the car, and a similar clunk when the pedal is released. With help, I was able to identify that the caliper assembly is moving and clunking against something, but I don't know what.

Suspension mods are Pedders Street Xa package and differential bushings with Pfadt trailing arms. I have been running fine on the setup for several weeks and then this noise started. Thanks for the help in advance.

Um, caliper is moving? Not possible. Is it bolted inplace like it should be?

Sorry, I'm sure my terminology is inaccurate. I think it could be described as the part that includes the pads/calipers and what they are mounted to. everything seems to be bolted in correctly, and everything was fine for several weeks after the install. I grant I could be mistaken, and if so, what else could cause that type of clunk?
